backend: define z_alloca() and use for both Unix and Windows;
replace double-slash comments with old-skool slash asterisk ones; define uint16_t etc for Windows ourselves and remove ms_stdint.h & stdint_msvc.h as no longer used; (backend (excepting test suite) now C89 compatible) LICENSE: move from backend to root and move COPYING to frontend, with copies in frontend_qt & backend_qt, so in where it applies; add LICENSE section from manual to root README
